Surely they don't expect user to revert to gcc-4.x. Surely inline doesn't
produce that much overhead on most current systems.
I think it is regarded as the same problem as
[https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65873]
I've picked some patches from gcc 5 branch that were added post-release, and
among them there is a fix referenced in the bug you mention. You can try it
for yourself if you are up to rebuilding gcc.
https://raw.githubusercontent.com/elkrejzi/system-management/master/patches/gcc-fixes.patch
I have ommited all of the test suite additions/modifications, documentation
and translations modifications and non-x86 architecture updates/fixes.
If so, looks as if current git versions of the intel driver will not be
usable with gcc-5.1.
But I only tried the git version to see if the segfault had already been
fixed.
Unfortunately, we are on the bleeding edge here, along with Arch.
Arch uses post-release GCC snapshots. So they already include all (most) patches
from gcc 5 branch.
For me the patch applies cleanly and the build is OK. I'm running tests now.
I need to update some packages in LFS anyway so I'll add this patch and start a
new build on a system that uses the intel driver to see if that fixes things up.
Since I'll need to build X on the new system, I may not get to that until
tomorrow.
